It is likely misunderstanding. Here are my steps:

Blank pattern
Track 1 Dual VCO
Live record eight beat pattern. Note trigs fall on steps 1, 3, 5… etc
Live record knob movement of filter cut-off
Disengage Live Recording

result:
Filter cut-off sweep recorded and pitch data “0” entered on empty trigs.

How do I disable the per step LFO? Do I have to do it manually on every step?

Thanks
